OILING SYSTEM.

Application filed September 24, 1925. Serial No. 58,468.

This invention relates in general to internal combustion engines and more particularly to a system of lubrication of certain portions of an engine of the Ford type.

One of the principal objections to the use of an engine of this type has been that when the oil in the crank case is low and when steep grades are encountered the oiling system fails to function properly. lVhen the oil in the crank case is low and steep upgrade is encountered the bearings at the front end of the engine are likely to be burned out while the steep down-grade is encountered the bands will not receive sutlicient lubrication and will be scared, their effectiveness thus being destroyed. Any person familiar with the use of engines of this type in mountainous or hilly country is well aware of the problem thus presented.

It is an object of my invention to provide oil deflectors so designed and mounted as to take fullest advantage of the oil particles being thrown off from the fly wheel of such an engine due to the centrifugal force incident to its operation, and to utilize the kinetic energy of these oil particles to build up the necessary pressures to insure lubrication at both ends of the engine irrespective of the grade.

Fig. 1 is a side elevation partly in section of my oiling system and applied to a motor of the character described;

Fig. 2 is a detailed view in perspective of my transmission oiling deflector;

Fig. 3 is a detailed View in perspective showing my forward deflector casing;

Fig. 1 is a central vertical section through my deflector casing. 7

Referring with greater particularity to the drawings my device is seen to comprise the following: a

To the usual engine 1 of the Ford type I have secured two deflectors 2 and 8. The deflector 2 has a flanged portion 5 provided with apertures 6 for the reception of any suitable securing means 7 to secure the same to the transmission case cover plate. The deflector 2 has a curved portion 42 which extends outwardly to a point adjacent the upper periphery of the fly wheel 21 of the engine, this extended portion being curved to face in a direction upstream of the flow of particles of oil being thrown off from the fly wheel due to the centrifugal. force incident to its rotation.

It Will be noted that the deflector portion 4 is so curved that the partimme'diatly ad acent the fly wheel is almost parallel thereto, the curve gradually changing the direction of flow of the deflected oil particle in such a manner as will ensure them being carried over against the flange 5 and thence forced downwardly and sprayed over the bands 9, 10 and 11. The rearward end of the deflector 2 is crimped at 8 to provide a gutter for the purpose of carrying oil to the clutch throw out member 12. The oiler 3 has a casing 13 mounted at 18 on a portion of the engine frame and has a mouth portion 14- forward of and adjacent to the upper outer periphery of the fly wheel, the mouth portion 14 facing in a direction upstream of the flow of particles of oil being thrown off a second mouth 15 adapted to receive oil particles falling under the influence of gravity and adapted to convey the same into the interior of the orifice and thence to the oil lead 21.

It will be seen from the above that the oil being thrown off from the flywheel will enter the mouth 14 with a considerable velocity and being deflected downwardly by the deflector 20 into the pipe 21 will create therein a pressure considerably in excess of the pressure which would exist if the oil in pipe 21 moved only under the influence of gravity.

From the foregoing it will be seen that I have provided means for ensuring lubrication both of the bands and of the front end of the motor irrespective of the grade under which the engine is operated as long there is suflicient amount of oil in the lower part of the crank case to cover the lower periphery of the fly wheel. Furthermore, it will be noted that the troubles so often present in an. engine of this kind, due to the clogging of the pipe, such as 21, willhave been obviated due to the fact that any stoppages which would otherwise be present due to the lint from the bands will be forced out by the pressure due to the kinetic energy of the oil particles.

I claim:

1. In an oiling system for an internal combustion engine of the character dcscribed, an oil deflector casing adapted to be secured to a portion of said engine forwardly and laterally of and near the, periphery of the fly wheel of said engine, said deflector combustion engine of the character described, an oil deflector casing adapted to be secured to a portion of said engine forward ly and laterally of and near the periphery of the fly Wheel of said engine, said deflector casing having a mouth portion facing up stream of the flow of oil particles being thrown from'tlie fly Wheel due to centrifugal force, an'oil pipe secured to said defiector casing, a curved deflector Within said casing adapted to deflect oil particles downwardly in said oil lead pipe and a second mouth portion upwardly of and rearwardly of said first named mouth portion adapted to receive-particles of oil falling under influence of gravity.

In testimony whereof I afiix my signature.
